Those who were left behind were glad on account of their sitting behind Allah's Messenger and they were averse from striving m Allah's way with their property and their persons, and said: Do not go forth in the heat. Say: The fire of hell is much severe in heat. Would that they understood (it) (81)

Therefore if Allah brings you back to a party of them and then they ask your permission to go forth, say: By no means shall you ever go forth with me and by no means shall you fight an enemy with me; surely you chose to sit the first time, therefore sit (now) with those who remain behind (83)

And whenever a chapter is revealed, saying: Believe in Allah and strive hard along with His Messenger, those having ampleness of means ask permission of you and say: Leave us (behind), that we may be with those who sit (86)

And the defaulters from among the dwellers of the desert came that permission may be given to them and they sat (at home) who lied to Allah and His Messenger; a painful chastisement shall afflict those of them who disbelieved (90)
